[PATCH] pgdat allocation and update for ia64 of memory hotplug: hold pgdat address at system running
This is a preparatory patch to make common code for updating of NODE_DATA() of
ia64 between boottime and hotplug.
Current code remembers pgdat address in mem_data which is used at just boot
time. But its information can be used at hotplug time by moving to global
value. The next patch uses this array.
